Whether it’s on Mars or at the kitchen table, entrepreneur Bart Womack wants to change what and how you eat.

But the CEO and founder of next-generation farming startup Eden Grow Systems is seeking crowdfunders to help feed the venture.

The company evokes images of a garden paradise on earth. But the idea behind the Houston-based NASA spinoff came from a more pragmatic view of the world. Womack’s company sells indoor food towers, self-contained, modular plant growth systems built on years of research by NASA scientists looking for the best way to feed astronauts in space.

The company has launched a $1.24 million regulated crowdfunding campaign to raise the money it needs to scale and expand manufacturing outside the current location in Washington state.

Additionally, the U.S. Air Force recently chose Eden as a food source for the U.S. Space Force base on remote Ascension Island, in the Atlantic Ocean, Womack tells InnovationMap. Another project with Space Center Houston is also in the works.

“We want to be the government and DOD contractor for these kind of next-generation farming systems,” he says.

The Houston-based company includes former NASA scientists, like recent hire Dr. L. Marshall Porterfield, of Purdue University, as an innovation advisor.

Womack, a former digital marketer, Houston public channel show host, night club owner and entertainment entrepreneur, left those ventures in 2012, after the birth of his first child. While taking a year to study trends research, in 2014, what he read intrigued and alarmed him.

“I’ll never forget, I came across a report from Chase Manhattan Bank….of the top 10 disruptive investment sectors, over the next decade,” he says. “At the very top of the list was food.”

His conclusions on the fragility of the world’s food supply system, due to overpopulation, and scarcer land, led him to launch Eden in 2017, funded by venture capital firm SpaceFund, Womack, his family, friends and angel investors.

Womack believes “black swan” events will only increase, disrupting the food supply system and further jeopardizing food supplies.

“We’re going to enter a period of hyper novelty in history,” Womack says.. "The system we’ve built for the last 100 years, the super optimized system, is going to begin to break apart."

To avert a centralized food production outcome, operated by corporate giants like Amazon or Walmart, Womack’s vision offers a decentralized alternative, leaving it in local hands.

With $2 million put into the company so far and a half million-dollars in sales last year, Womack argues that Eden has achieved much and can make food independence within reach for everyday families.

The company commercialized NASA technology to fill what it viewed as “a huge gap within the controlled…agricultural space.”

The tower is the building block of a modular, automated and vertical indoor plant growth system, with calibrated misting, fans, and LED lighting, controlled by an app.

The company website touts the towers as an easy way to grow plants like lettuce, carrots, tomatoes, and potatoes, with little water, no soil, and lots of air, without the expense and work of cultivating an earth-based garden.

For those who want to eat more than greens, the towers provide a way to breed fish and shrimp in an aquaponic version, recycling fish waste as plant fertilizer.

However, big plans come with big costs. The towers range in price from $5,000 to $7,000, although payment plans for those who qualify make it affordable.

Eden has sold around 100 of their towers so far, to a variety of customers. But rising costs and shipping delays have led to a a three-month backlog.

The manufacturing and shipping associated with larger installations means that even if the company made a million-dollar sale, delivery of the product would take a year.

“One of the hardest things…as a start-up, the last couple of years, is trying to narrow down exactly where the biggest payback is,” Womack says. “There is the lower hanging fruit, of small sales to individual buyers, but there’s the larger fruit of institutional buyers. But they can take months and years to convert into an actual buyer.”

Customers include several universities, including Texas A&M University and Prairie View A&M University, and talks are underway with other large academic institutions.

For now, attracting investors so the company can reach its funding goal poses the biggest challenge.

“Texas investors are very, very hard-nosed, and they’re not like West Coast investors. They want to understand exactly how they’re going to get their money back, and exactly how quickly,” he says.

Womack says the crowdfunding round would allow the company to expand manufacturing operations into Houston, deliver product faster, and invest in advertising.

“When we complete this round, and become completely self sufficient, we’re planning on moving to a $25 million valuation,” Womack says. “We can show, given money, we can scale the company.”

The city of Nassau Bay, next to NASA’s Johnson Space Center, has purchased towers and plans to purchase more, not for the production of food, but to grow ornamental flowers.

Womack says that city officials there found that it’s cheaper to grow the decorative plants themselves, rather than buying them.

The towers are adaptable, and can grow not only food but cannabis and other plants, and if buyers want to use them other purposes, that adds to the product’s appeal, Womack says.

Eden has also sold some towers to Harris County Precinct 2 and the city of Houston, as part of a project he says will turn food deserts throughout the area into “food prosperity zones.”

“Our goal is to be the farming equivalent of Boeing,” Womack says.

1PointFive signs latest deal, shares update on $1.3B carbon removal project

DAC deal

Houston-based 1PointFive, a subsidiary of Occidental Petroleum Corp., has secured another buyer of carbon dioxide removal credits for its $1.3 billion STRATOS project as it moves toward operation.

Bain & Company, a Boston-based consulting firm, has agreed to purchase 9,000 metric tons of carbon dioxide removal (CDR) credits from the direct air capture (DAC) facility over three years, according to a news release. DAC technology pulls CO2 from the air at any location, not just where carbon dioxide is emitted.

The deal is Bain's first purchase of DAC removal credits. The company has developed a program that helps clients purchase carbon credits from a range of carbon-removal technologies.

"We are proud to partner with 1PointFive and add them to our portfolio of engineered carbon removal technologies," Sam Israelit, Bain’s chief sustainability officer, said in the news release. "Their track record for developing DAC technology, coupled with their deep understanding of what it takes to deliver large-scale infrastructure projects, uniquely positions them to be a leader in this emerging segment.”

“We believe this agreement demonstrates continued momentum for the solution while supporting the development of vital domestic infrastructure,” Anthony Cottone, president and general manager of 1PointFive, added in the release.

Bain joins others like Microsoft, Amazon, AT&T, Airbus, the Houston Astros and the Houston Texans that have agreed to buy CDR credits from STRATOS.

The Texas-based STRATOS project is being developed through a joint venture with investment manager BlackRock and is designed to capture up to 500,000 metric tons of CO2 per year. The U.S Environmental Protection Agency approved Class VI permits for the project last year.

1PointFive says STRATOS is "progressing through start-up activities." The company shared in a LinkedIn post that Phase 1 of the project is expected to go online in Q2, with Phase 2 ramping up through the remainder of 2026.

Houston researcher develops efficient method to cool AI data centers

cool findings

A University of Houston professor has developed a new cooling method that can remove heat at least three times more effectively from AI data centers than current technologies.

Hadi Ghasemi, a distinguished professor of Mechanical & Aerospace Engineering at UH, published his findings in two articles in the International Journal of Heat and Mass Transfer. The findings solve a critical issue in the growing AI sector, according to UH.

High-powered AI data centers generate huge amounts of heat due to the GPU and operating systems they use with extreme power densities, which introduce complex thermal challenges. Traditionally, cooling methods, like microchannels, which use flow and spray cooling, have had limitations when exposed to extreme heat flux, according to UH.

Ghasemi’s research, however, found a more effective way to design thin-film evaporation structures to release heat from data centers and electronics at record performance.

Ghasem’s solution coupled topology optimization and AI modeling to determine the best shapes for thin film efficiency, ultimately landing on a branch-like structure—resembling a tree.

The model found that the “branches” needed to be about 50 percent solid and 50 percent empty space for optimum efficiency, and that they could sustain high heat fluxes with minimal thermal resistance.

“These structures could achieve high critical heat flux at much lower superheat compared to traditionally studied structures,” Ghasemi said in a news release. “The new structures can remove heat without having to get as hot as previous removal systems.

Ghasemi’s doctoral candidates, Amirmohammad Jahanbakhsh and Saber Badkoobeh Hezave, also worked on the project. The team believes their results show the impact of a physics-aware, AI design and can help ensure reliability, longevity and stability of AI data centers.

“Beyond achieving record performance, these new findings provide fundamental insight into the governing heat-transfer physics and establishes a rational pathway toward even higher thermal dissipation capacities,” Ghasemi added in the release

Texas federal judge allows lawsuit against California AG over ExxonMobil remarks

In the News

A federal judge in Texas ruled that ExxonMobil can bring a defamation lawsuit against California’s attorney general over comments about the company’s plastic recycling efforts.

U.S. District Judge Michael J. Truncale in the Eastern District of Texas said in a ruling in February that California Attorney General Rob Bonta cannot claim official immunity in regards to several statements he made, including one in a campaign email sent to Texas residents.

Bonta sued Exxon in September 2024, saying that the oil giant encouraged consumers to purchase plastics products with the promise that the products would be recycled. He said less than 5% of plastic is recycled into another plastic product, and that recycling processes touted by Exxon don't work. Exxon said the problem is with California's recycling system.

Exxon later sued Bonta in his individual capacity and environmental groups for defamation, saying that the comments harmed current and future business contracts. The lawsuit was filed in Texas, near its principal place of business.

Truncale dismissed the lawsuit against the environmental groups but allowed it to proceed against Bonta.

The judge pointed to a campaign email Bonta sent to Texas residents saying that only 5% is recycled and the rest ends up in the environment and in our bodies: “Exxon Mobil knew, and Exxon Mobil lied.” Bonta, a Democrat, argued he was simply updating email recipients on his office's activities.

But Truncale said a campaign contribution link on the email turned the communication into a campaign activity not protected by immunity in Bonta's official capacity as attorney general.

“Here, the contribution request betrays the email's true nature: a campaign promotion. Campaigning is not within Bonta's scope of employment,” the judge wrote.

Bonta has filed a notice of appeal.

“The Attorney General looks forward to vigorously litigating this case, and is proud to advance his lawsuit against ExxonMobil,” his press office said.

ExxonMobil said in a statement that the “campaign of lies designed to derail our advanced recycling business must stop.”
